My observation going back to the 70’s was that when you put a 50mm or so lens on a DSLR and looked through viewfinder with both eyes open, the size of objects appeared very close to the same

And this is the important point, not the angle of view. With a 43mm lens, the sizes would appear even closer.

This depends on viewfinder magnification. On my 35mm SLR sizes look the same at 52mm, but on my A7III it is 65mm and on my RX100 it never happens because the lens isn't long enough.

Paul Pasco said "through viewfinder with both eyes open, the size of objects appeared very close to the same" and I replied "With a 43mm lens, the sizes would appear even closer". Neither of us said they would appear exactly the same through the viewfinder as with the naked eye.
